[0030] Example 1

[0031] See also Figure 1-3 As shown, this embodiment discloses a touch panel 1, including: an upper shell 11, a touch film 12, a vibration feedback device 13 and a bottom shell 14; one side of the bottom shell 14 is open and provided with a accommodating cavity 141, and the upper shell 11 is covered on the open side of the bottom shell 14; the touch film 12 is connected to a side surface of the upper shell 11 close to the bottom shell 14; the vibration feedback device 13 is provided in the accommodating cavity 141 and connected to the bottom shell 14, and the vibration feedback device 13 is used to drive the upper shell 11 and the touch film 12 to vibrate.

[0032] During specific implementation, the user touches the upper shell 11 with his fingertips, causing the upper shell 11 to squeeze the touch film 12; the touch film 12 captures the touch signal and converts the touch signal into an electrical signal; the electrical signal is transmitted to the controller of the corresponding operation and fed back to the vibration feedback device 13; the vibration feedback device 13 is activated, causing the upper shell 11 and the touch film 12 to vibrate, and the upper shell 11 transmits the vibration to the user's fingertips, prompting the user that the touch panel 1 has responded to the switch control.

[0033] The touch panel 1 of this embodiment is provided with a touch film 12, which realizes keyless touch control, helps to realize multi-touch and slide unlock, provides rich and intelligent interaction methods, improves the flexibility and convenience of interactive operations, and thus improves user experience; the touch film 12 is not restricted by strong light or specific environmental conditions, and combined with the built-in vibration feedback device 13 of the touch panel 1, it can provide users with intuitive tactile feedback, so that users do not need to frequently shift their eyes to confirm the touch position, effectively reducing distraction during driving, thereby improving driving safety.

[0034] Specifically, it also includes: a control board 15; the control board 15 is arranged in the accommodating cavity 141 and is connected to the bottom shell 14; the vibration feedback device 13 and the touch film 12 are electrically connected to the control board 15. After receiving the touch signal sent by the touch film 12, the control board 15 sends the corresponding operation instruction to the actuator, and sends a vibration signal to the vibration feedback device 13 to drive the upper shell 11 to vibrate and feed back the interaction results to the user. The touch film 12, the vibration feedback device 13 and the control board 15 are integrated in the accommodating cavity 141, which can effectively reduce the impact of external electromagnetic interference on the performance of the touch panel 1; the control board 15 provides the needs of function expansion and upgrading, and is convenient for adding functional modules according to user needs, such as fingerprint recognition module, sound feedback module, etc., which helps to improve the personalization of the control panel and user preference.

[0035] Specifically, it also includes several optical feedback components, which are located within cavity 141. These components provide visual feedback to the user, helping them accurately determine the results of touch operations in low-light or restricted vision. The combination of visual feedback and vibration feedback provides a dual confirmation mechanism, greatly enhancing the intuitiveness of touch operations and improving the interactive experience of touch panel 1.

[0036] Specifically, the optical feedback assembly includes a reflector 16 and a display light 17. Reflector 16 is connected to the upper housing 11 and located on the side of the touch film 12 near the bottom housing 14. Reflector 16 covers display light 17, which is electrically connected to the control board 15. Reflector 16 isolates the light from adjacent display lights 17, preventing it from being reflected onto adjacent optical feedback components and causing interference. When the control board 15 receives a touch signal from the touch film 12 and processes it, it activates display light 17, causing it to emit light to illuminate a specific area or edge of the upper housing 11.

[0037] Preferably, the reflector 16 is shaped like a trumpet; the end with a smaller opening of the reflector 16 is provided with a display light 17, and the end with a larger opening of the reflector 16 is connected to the upper housing 11. The trumpet-shaped configuration not only avoids visual interference caused by light scattering, but also helps guide light to focus and illuminate a specific area of ​​the touch panel 1.

[0038] Preferably, the display light 17 is an LED lamp bead; there are two LED lamp beads corresponding to one display light 17. Each display light 17 is configured with two LED lamp beads, which enhances the brightness and uniformity of the light, provides the user with eye-catching visual feedback, and thus significantly improves the interactive experience of the touch panel 1 and user satisfaction.

[0039] Specifically, the bottom housing 14 is provided with a mounting plate 142, which extends from the top of the bottom housing 14 toward the accommodating cavity 141. The mounting plate 142 is located on the side of the reflector 16 away from the touch film 12. The vibration feedback device 13 is mounted on the mounting plate 142, and the output end of the vibration feedback device 13 is connected to the reflector 16. The mounting plate 142 and the vibration feedback device 13 are located between the reflector 16 and the control board 15, which improves the compactness of the touch panel 1 and prevents vibration from interfering with the optical feedback component. The vibration feedback device 13 also acts directly on the reflector 16, allowing vibration to be efficiently transmitted to the upper housing 11, thereby enhancing the tactile feedback of the user's fingertips and improving the user experience.

[0040] In this embodiment, the vibration feedback device 13 is a vibration motor, the output end of which is connected to the reflector 16. It is understood that in other embodiments, a motor, an electromagnet assembly, a piezoelectric ceramic vibrator, or other vibration feedback devices 13 may be used to replace the vibration motor according to actual needs.

[0041] Specifically, it also includes a proximity sensor 18, which is located in the accommodating cavity 141 and electrically connected to the control board 15. The proximity sensor 18 is used to detect the proximity of a contact object to the touch panel 1. The proximity sensor 18 and the touch film 12 provide dual sensing. When a user's finger approaches the touch panel 1, the proximity sensor 18 can pre-detect and send a proximity signal to the control board 15, initiating a corresponding pre-processing procedure. This improves the touch panel 1's responsiveness and enhances its intelligence. The proximity sensor 18 also facilitates gesture recognition and hover sensing, allowing users to control related functions, such as adjusting the volume and turning the air conditioner on and off, without touching the touch panel 1, significantly enhancing the user experience.

[0042] In this embodiment, the touch film 12 is a capacitive touch film 12. Capacitive touch films 12 feature high sensitivity, low power consumption, and a short response time. When a user lightly touches the upper housing 11, the touch film 12 is squeezed, causing the electric field across the touch film 12 to change, thereby triggering a touch signal. The area of ​​the electric field change indicates the user's touch area, which is then fed back to the control panel 15. This allows the control panel 15 to activate the corresponding function and illuminate the indicator light 17 in the corresponding area. It is understood that in other embodiments, pressure-sensitive touch films 12, projection-sensitive touch films 12, or other touch films 12 may be used in place of the capacitive touch film 12, depending on actual needs.

[0043] Specifically, the control panel 15 is provided with a main controller 151, a vibration feedback device driver unit 152, a sensing detection unit 153, and a display light driver unit 154. The vibration feedback device driver unit 152, the sensing detection unit 153, and the display light driver unit 154 are electrically connected to the main controller 151. The vibration feedback device 13 is electrically connected to the vibration feedback device driver unit 152, the touch film 12 and the proximity sensor 18 are electrically connected to the sensing detection unit 153, and the display light 17 is electrically connected to the display light driver unit 154. The main controller 151 coordinates the operations of the vibration feedback device driver unit 152, the sensing detection unit 153, and the display light driver unit 154, enabling on / off control of the vibration feedback device 13, the touch film 12, the proximity sensor 18, and the display light 17, thereby enhancing the intelligence level of the control panel.

[0044] Specifically, the control board 15 is equipped with a DC-DC converter unit 155, an LDO unit 156, and a LIN transceiver unit 157. The DC-DC converter unit 155 is used to connect to an external power source to power the control panel. The input and output of the LDO unit 156 are respectively connected to the DC-DC converter unit 155 and the main controller 151, which is used to reduce the voltage and provide power to the main controller 151. The LIN transceiver unit 157 is used to connect the main controller 151 to the LIN bus to send control commands to the corresponding actuators. The main controller 151 sends commands to actuators such as the audio system, air conditioner, and ceiling light via the LIN bus to respond to user operations. The DC-DC conversion unit 155 and the LDO unit 156 reduce the 12V external DC voltage to 5V and 3.3V respectively, which are used to power the display light 17 and the main controller 151 respectively, providing operation guarantee for the touch panel 1, while also avoiding overvoltage of the main controller 151, the vibration feedback device 13, the touch film 12, and the display light 17, ensuring the safety and reliability of the control panel.

[0045] Preferably, the main controller 151 is an MCU. An MCU (Microcontroller Unit) is a low-power, scalable, and cost-effective integrated circuit chip. It has data processing capabilities, which helps reduce the number of LIN bus transmissions and the data processing burden of the vehicle's main control. It also helps users customize or add control functions according to their needs, thereby increasing the personalization of the control panel.

[0046] Specifically, the upper housing 11 is light-transmissive. This facilitates the transmission of light from the display light 17 to the operating surface of the display panel, helping the user intuitively perceive changes in the display light 17. In other embodiments, the upper housing 11 can be hollowed out instead of being light-transmissive, providing a channel for the light from the display light 17 to diffuse, depending on actual needs.

[0047] Specifically, the upper shell 11 includes: a texture layer, a first glue layer, a pattern layer, a second glue layer, an elastic layer, and a third glue layer, which are arranged in sequence from top to bottom. The texture layer, the first glue layer, the pattern layer, the second glue layer, the elastic layer, and the third glue layer are arranged in sequence from the side of the upper shell 11 away from the touch film 12 to the side close to the touch film 12. The design of the texture layer increases the user's touch comfort and anti-slip performance, while also improving the overall aesthetics of the touch panel 1; the pattern layer is printed with ink and can be customized with different icons according to functional requirements to provide users with control prompts. For example, when turning on the dome light function, the corresponding area of ​​the pattern layer is set to the shape of a light bulb, which improves the user's operation convenience; the elastic layer is made of 3D mesh material. 3D mesh is a three-dimensional mesh structure with high flexibility and elasticity, which can adapt to the deformation of the touch panel 1 when it is subjected to pressure. The provision of the first glue layer, the second glue layer, and the third glue layer prevents the presence of soft fillers such as foam in the upper housing 11 , which would affect the conductive properties of the touch film 12 and the light transmittance of the upper housing 11 .

[0048] Specifically, the texture layer is 0.3-0.5mm thick, the first glue layer is 0.05mm thick, the pattern layer is 0.05mm thick, the second glue layer is 0.05mm thick, the elastic layer is 1-3mm thick, and the third glue layer is 0.12mm thick. The thin upper housing 11 reduces the thickness of the touch panel 1, conserving its footprint and facilitating flexible installation in multiple areas of the vehicle. The reduced thickness of the upper housing 11 also facilitates receiving user touch pressure and transmitting it to the touch film 12, reducing pressure loss while preventing damage to the touch film 12 due to excessive deformation, thereby ensuring the structural stability of the touch panel 1.

[0049] Specifically, the upper housing 11 and the bottom housing 14 are welded together. This welding process strengthens the overall structural strength of the touch panel 1, improves the sealing, waterproof and dustproof properties of the touch panel 1, and reduces the failure rate of the touch panel 1, providing users with a more reliable and stable touch experience.

[0050] Example 2

[0051] See also Figure 1-5As shown, this embodiment discloses a touch control system, comprising: an interior panel 2 and the touch panel 1 of the first embodiment; the touch panel 1 is embedded in the interior panel 2, and there is a gap between the touch panel 1 and the interior panel 2. The interior panel 2 is an interior panel of the car, and the touch panel 1 can be set on the interior panel 2. In a specific implementation, a mounting hole is reserved on the interior panel 2 to install the touch panel 1 in the mounting hole. When the vibration feedback device 13 is in operation, it drives the reflector 16, the touch film 12 and the upper shell 11 to vibrate, causing the upper shell 11 to shake to a certain extent, so a gap is set between the touch panel 1 and the interior panel 2 to facilitate the vibration of the upper shell 11.

[0052] Preferably, the distance between the touch panel 1 and the interior panel 2 is 0.3-0.5 mm. This 0.3-0.5 mm gap prevents direct contact between the touch panel 1 and the interior panel 2, reduces noise and friction loss caused by vibration, and extends the service life of the touch panel 1 and the interior panel 2. It also avoids excessive gaps, ensuring the aesthetics and neatness of the touch system.

[0053] Preferably, a rubber buffer pad (not shown) is provided between the touch panel 1 and the interior panel 2. The rubber buffer pad has the function of filling the gap and maintaining a stable distance between the touch panel 1 and the interior panel 2, and also has excellent shock absorption and sound insulation performance.

[0054] Example 3

[0055] See also Figure 1-5 As shown, this embodiment discloses a vehicle, including: the touch control system of embodiment 2.

[0056] The interior of the car of this embodiment is integrated with a touch system that is flexible in operation and highly safe, which significantly improves the vehicle's intelligence level and user interaction experience. The personalized customization capabilities and extended functions of the touch panel 1 and the touch system also provide users with more choices, further enhancing the vehicle's attractiveness and market competitiveness.

[0057] This embodiment provides a touch panel, a touch system and a vehicle, which are equipped with a touch film to achieve keyless touch control, facilitate multi-touch and slide unlocking, provide rich and intelligent interaction methods, improve the flexibility and convenience of interactive operations, and thus improve the user experience; the touch film is not restricted by strong light or specific environmental conditions, and combined with the built-in vibration feedback device of the touch panel, it can provide users with intuitive tactile feedback, so that users do not need to frequently shift their eyes to confirm the touch position, effectively reducing distraction during driving, thereby improving driving safety.
